Theother portions of the cell making up this assembly are plainly shown in theillustration. Fig. 51 contains an illustration of a typical battery installationin which glass jars are used. The method of supporting the cells in racksor tiers is plainly illustrated, as are also the methods of making the inter-cell connections as well as the terminal or end-cell connections with the mainservice bus bars. The sand trays and glass petticoat insulators are alsoplainly Pig. 51.—Glass Jar Battery Installation. Some types of glass Jar installations provide for the support of theelement by means of a set of bridges secured to the bottom of the jar verysimilar to those described for the portable types of hard rubber jars, withthe exception, however, that these bridges are secured to the bottoms of theglass jars by means of sealing compound or other such method. Fig. 53contains an illustration of a glass jar cell assembly incorporating this featureof design. These particular cells are securely sealed by means of acid-proofsealing compound, the terminal posts passing through this bed of inter-cell connectors and method of connecting the cells together arealso shown. Fig. 53 contains a disassembled view of a Plante type cell assembly, suchas used in glass jar installations. The details
